    We identified protein domains in LUCA (#LastUniversalCommonAncestor). Their distinctive #AminoAcid usage reveals the order amino acids were added to the #GeneticCode, based mostly on size. Older proteins hint at earlier alternative codes. 1/15 pnas.org/doi/10.1073/pnas.2410 #astrobiology #phylostratigraphy #sulfur #metalloproteins

    All #Life On #Earth Originates From #OneAncestor, Older Than Previously Believed
    A new study estimates that #LUCA, the #LastUniversalCommonAncestor of all life on Earth, existed around #4billionyearsago.

    Searching for #LUCA, the #firstlifeform from which all other life descended
    #Scientists have said the #lastuniversalcommonancestor could have formed just 300 million years after the #earthformed.

    @RobLanfear I use #phylogenetics for studying long-term trends in #protein #evolution, classifying proteins by age since birth, and looking for biases in retention and in descent with modification. We are currently interested in reconstructing the #proteome of the #LastUniversalCommonAncestor.
